HERF1006G Equivalent & Substitute Parts

Part Overview

The HERF1006G is a diode array rectifier manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode design with 600 V reverse voltage rating and 10 A average rectified current per diode. The device is packaged in a TO-220-3 Full Pack with isolated tab configuration for through-hole mounting applications.

This part is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional compatibility within the specified electrical and mechanical parameters. Substitute parts must satisfy the same voltage class, package configuration, and thermal operating range to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HERF1006G is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode (topology must be identical)
• Voltage - DC Reverse (Vr) (Max): 600 V (minimum requirement; higher ratings are acceptable)
• Package / Case: TO-220-3 Full Pack, Isolated Tab (physical and thermal interface compatibility)
• Supplier Device Package: ITO-220AB (pin configuration and isolation characteristics)
• Mounting Type: Through Hole (assembly method compatibility)
• Operating Temperature Range: -55°C to 150°C (thermal envelope compatibility)

Acceptable Variation Parameters:

• Current - Average Rectified (Io): Substitute parts rated at or above 10 A per diode are acceptable
• Voltage - Forward (Vf): Substitute parts with equal or lower forward voltage drop are acceptable
• Reverse Recovery Time (trr): Substitute parts with equal or faster recovery characteristics are acceptable
• Current - Reverse Leakage: Substitute parts with equal or lower leakage current are acceptable

Substitute parts that meet or exceed the HERF1006G specifications in current rating, forward voltage performance, and recovery characteristics provide functional equivalence for direct replacement applications.

Engineering Selection Recommendations

FEPF16JTHE3_A/P (Vishay General Semiconductor - Diodes Division)

This substitute part maintains full electrical and mechanical compatibility with the HERF1006G. The FEPF16JTHE3_A/P is rated for 8 A average rectified current per diode, which is lower than the HERF1006G 10 A rating. However, the part demonstrates superior performance characteristics with a reverse recovery time of 50 ns (compared to 80 ns) and forward voltage of 1.5 V @ 8 A. The part is currently active in production and carries AEC-Q101 automotive qualification, indicating robust manufacturing and quality standards. ROHS3 compliance and identical thermal operating range ensure direct compatibility. This substitute is suitable for applications where the 8 A current rating meets system requirements.

SDURF1060CT (SMC Diode Solutions)

This substitute part provides electrical and mechanical compatibility with identical 600 V reverse voltage rating and TO-220-3 Full Pack, Isolated Tab packaging. The SDURF1060CT demonstrates superior reverse recovery time of 50 ns and lower reverse leakage current of 5 µA @ 600 V. The part is currently active in production. ROHS3 compliance and identical thermal operating range are maintained. The average rectified current specification is not provided for this part; therefore, current rating compatibility must be verified against specific application requirements. REACH Status is listed as Affected, requiring compliance verification for applications subject to REACH regulations.

Both substitute parts satisfy the critical matching parameters of diode configuration, voltage rating, package type, and thermal operating range. Selection between substitutes depends on application current requirements and regulatory compliance obligations.

Frequently Asked Questions (FAQ)

Q: Can the FEPF16JTHE3_A/P replace the HERF1006G in all applications?

A: The FEPF16JTHE3_A/P is mechanically and electrically compatible with the HERF1006G in terms of package configuration, voltage rating, and thermal operating range. However, the FEPF16JTHE3_A/P is rated for 8 A average rectified current per diode, compared to the HERF1006G 10 A rating. Substitution is valid only for applications where the circuit current requirements do not exceed 8 A per diode.

Q: What is the significance of the TO-220-3 Full Pack, Isolated Tab package?

A: The TO-220-3 Full Pack, Isolated Tab configuration specifies the physical form factor, pin count, and thermal interface characteristics. The isolated tab design provides electrical isolation between the device tab and the mounting surface, which is critical for certain circuit topologies. All substitute parts maintain this identical package specification, ensuring mechanical and thermal compatibility without modification to PCB layout or mounting hardware.

Q: Are the substitute parts suitable for automotive applications?

A: The FEPF16JTHE3_A/P carries AEC-Q101 automotive qualification, indicating compliance with automotive industry reliability and quality standards. The SDURF1060CT does not specify automotive qualification in the provided parameters. Selection for automotive applications must be based on specific qualification requirements of the end application.

Q: What is the difference in reverse recovery time between the main part and substitutes?

A: The HERF1006G specifies a reverse recovery time of 80 ns. Both substitute parts (FEPF16JTHE3_A/P and SDURF1060CT) specify 50 ns reverse recovery time. Faster reverse recovery time indicates improved switching performance and reduced switching losses, representing a performance improvement over the original part.

Q: How do forward voltage characteristics compare across the three parts?

A: Forward voltage specifications are measured at different current levels: HERF1006G at 1.7 V @ 10 A, FEPF16JTHE3_A/P at 1.5 V @ 8 A, and SDURF1060CT at 1.55 V @ 5 A. Direct comparison requires normalization to identical current levels. At lower current levels, forward voltage typically decreases; therefore, the FEPF16JTHE3_A/P and SDURF1060CT demonstrate lower forward voltage characteristics at their respective rated currents.

Q: What does ROHS3 Compliant status indicate?

A: ROHS3 Compliant indicates that the component meets the Restriction of Hazardous Substances Directive 3 requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. All three parts (HERF1006G, FEPF16JTHE3_A/P, and SDURF1060CT) are ROHS3 compliant, ensuring regulatory compliance for applications subject to ROHS requirements.

Q: What is the significance of REACH Status in the SDURF1060CT specification?

A: REACH Status indicates compliance with the European Union's Registration, Evaluation, Authorization and Restriction of Chemicals regulation. The SDURF1060CT is listed as REACH Affected, meaning the component or its manufacturing process is subject to REACH requirements. Applications subject to REACH regulations must verify compliance with specific substance restrictions and documentation requirements.

Q: Can the SDURF1060CT be used as a direct replacement if current rating is not specified?

A: The SDURF1060CT does not provide an average rectified current specification in the available parameters. Direct substitution requires verification that the unspecified current rating meets or exceeds the application circuit requirements. Contact the manufacturer or authorized distributor for complete electrical specifications before implementing this substitute in current-critical applications.
